        <p>Activity 12 is distinctive in that you are welcome to try as much as you want at any one time and to try as often as you wish. However, you have to get <strong>full marks</strong> on it in order to proceed to the second part of TMA 01, Activity 15.</p>

        <p>There are 30 questions, which can be attempted in any order. When you are ready to attempt a question, choose your answer and then \'Submit\'. You will get feedback. If you need to try again, follow the same process. When you are satisfied with your answer to one question, go on to another. Remember to choose \'Submit\' for each answer that you want to be saved.</p>

        <p>You do not have to do the questions all at one sitting: at any time you can choose \'Save without submitting\'. This saves the current state of all questions so you can come back later to do some more.</p>

        <p>When you are satisfied with your answers to all 30 questions, choose \'Submit all and finish\'. This marks all questions, closes the current quiz attempt and gives the PCAP team formal notification that you have successfully completed this part of the TMA. <strong>Should you inadvertently choose this option you will need to start from scratch when you next attempt the task.</strong></p>',
